WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 417,179, dated December10, 1889.

Application filed June 13, 1889. Serial No. 314,083. (No model.)

To all whom t may concern:

Beit known that I, DANIEL IIARTLEY, of Olathe, in the county of Johnsonand State of Kansas, have invented certain new and useful Improvementsin Vindow-Screens, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specific-ation, and in which- Figure I is a perspectiveview of my improved screen in position, showing a portion of thewire-gauze broken away in order to more clearly illustrate certainportions of the device. Fig. II isa vertical section taken on line II IIof Fig. I. Fig. III is a transverse section taken on line III III ofFig. I. Fig. IV is a front view of one of the screenguides. Fig. V is anenlarged detail perspective view of the screen-frame.

My inventionrelates to an im provementin window-screens; and it consistsin features of novelty hereinafter described, and pointed out in theclaims.

Referring to t-he drawings, l represents the window-frame, to which isattached two guides or strips 2. The guides 2 serve to hold the screenin position inthe frame, but permit it to move or slide in a verticaldirection.

-i represent the frame, which is made in four sections, the sectionsbeing riveted to each other and to the wire-gauze 5. I form thescreen-frame of metal, and prefer to make it of tin, but do not coniinemyself to this material. The top and bottom sections 3 of the frame areformed into a T shape, the ribs 6 servingto strengtl'ien the frame andto give the same a neat appearance.

8 il represent two parallel extensions ol' thc frame, between which thetop and bottom of the wire-gauze is clamped. The gauze may be furthersecured by rivets passing through the extensions and the wire-gauze. Theside sections l ofA the frame are formed with V-shaped extensions 10 l1,a rib 12, and parallel extensions 13 la. Between the parallel extensionsthe side of the gauze is held. The extensions may be held firmlytogether by means of rivets. Between the V- shaped extensions 10 11 areV- shaped grooves l5. The guides E. it into the V- shaped grooves 15,thus forming a guideway between thc screen and the window-frame, and

as the guides fit loosely in the grooves the screen may be raised orlowered at will, and as the guides only extend about half-way up thewindow-frame it will be seen that the screen may be removed entirelywhen so desired. The rib 12 gives strength to the frame, the same beingessential, as where the frame is made of so light a material as tin itisnecessary that it be formed in such a shape as to give it strength.

1G represents a clamp or bracket which extends in a transverse directionacross the screen, and whichis riveted thereto. To this bracket issecured a rubber strip 17. The object of the strip 17 is to ll up thespace between the screen and the window-pane (see Fig. I) in order toprevent insects from passing through between the screen and pane when'the lower sash is only raised a portion of the way.

1S represents the window-sash, and 19 the window-panes.

By my improved method of making the very light material (such as tin)and still make the frame perfectly rigid. The sections may be stampedont and then formed into the shape described, or otherwise manufactured,as may be desired.

I claim as my inventionl. As a new article of manufacture, awindow-screen frame formed of thin metal having V- shaped grooves andstrengthening-ribs projecting at an angle to the frame, substantially asset fort-h.

2. A win dow-screen frame composed of sheet metal having V-shapedgrooves in its outer edges and strengthening-ribs projecting at an angleto the frame, substantially as set forth.

3. In a window-screen, the combination of the top and bot-tom sectionsof the frame formed of sheet metal bent substantially in a T shape, andthe side sections of sheet metal formed with a strengthening rib, saidT- shaped projection and strengthening-rib extending beyond t-he line ofthe screen in order to protect the same, substantially as described, andfor the purpose set forth.
